Delimbe seeder T20H 400L

  • $7,700.00

The Delimbe T20 air seeder is a multi-purpose 12 volt applicator with an hydraulic blower fan for distributing most small seeds up to 40 feet wide.

The T20 seeder are equiped with 2 individual metering shaft drived by 2 electric motors that can be activate individually.

The seeding flow rate is from 2 to 180 pounds/acres depending of the ground speed and the application width.


400 liter tank capacity (11.5 bushels)

16 outlet air distributor (available plug for less outlet need)                             

Empty weight: 220 pounds                      

Dimensions: 27 inch wide  (total)                      

                      50 inch high  (total)                                        

                      35 inch long  (tank)

                      84 inch long  (total)


Blower pipe: 40 mm diameter               

Supply voltage:12 volts

Hydraulic fan requires 0-5 gallon/min max oil supply and a free flow return (push-pull plug included)

12 feet of hydraulic flexible is included.

 Three control systems are available:

1. Standard includes control box with on/off and speed variation for calibration. 

2. Additional option BSelf contained GPS control system (recommended for variable seeding rates)


Fit the Delimbe T20 air seeder in the centre of the implement and check it is securely bolted into position.

The T20 seeder draws air in below the fan unit so allow room for air to circulate and avoid putting a flat plate directly under the unit.

When fitting the pipes to the outlets the pipes should always slope downhill to avoid any potential blockages.

The spreader plates can be instal with an seperate distance up to 36 inch. 

If sufficient power is not provided from the socket within the tractor cab, then source power direct from the tractor battery and protect with a 30 amp fuse.

Three types of seed rotor are include with the seeder depending on the size of seed to be sown. Green for small seeds, stainless steel (yellow) for larger seeds and red for large seeds and grass seed.


All applicators are calibrated in kilogrammes per hour.
The calibration calculation is:

Working width(meter) x forward speed (kilometer/hour) which gives you hectares per hour. Now multiply the hectares per hour by the desired seed rate and the result is the kilogrammes per hour. Now look in the settings table for the chosen rotor and the kg/hr has a number which relates to the dial setting on the control box.


A Delimbe T20  mounted on a 3 metre cultivator seeding alfalfa with a green rotor traveling at 10km/hour at a seed rate of 4kg/hectare:

3 metre x 10 km/hr = 30,000 m2 = 3.0 ha/hour

3 ha/hr x 4 kg/ha = 12 kg/hr

12 kg/hr in the green rotor settings table is between dial setting 8 or 9 on the dial. Now set the dial between 8 or 9 on the control box dial. 

Now check the calibration setting. Switch off the hydraulic blower fan and open the calibration door located under the meetering shaft. Run the applicator for one minute, collect the seed, weigh it and multiply by 60 to check the flow rate per hour. If necessary adjust the control box variator up or down and run the test again to check the flow rate.
